Coordination for smooth beamforming

A method for wireless communications at a first wireless communication device, comprising:

• communicating, with a second wireless communication device, control signaling that indicates that the first wireless communication device is scheduled to transmit a beamformed message to the second wireless communication device, and wherein the control signaling includes an indication that the second wireless communication device is to apply channel smoothing filtering to the beamformed message;
• transmitting, to the second wireless communication device and in association with the control signaling, the beamformed message via a set of frequency tones, wherein one or both of the beamformed message satisfies a delay spread threshold or a phase alignment of the beamformed message associated with the set of frequency tones satisfies a phase alignment threshold;
• and
• applying a first v-smooth filtering process in a first tone domain to a packet mapped to the set of frequency tones;
• or
• applying the first v-smooth filtering process in the first tone domain to the packet and applying a second v-smooth filtering process to the packet in a second tone domain subsequent to applying the first v-smooth filtering process, wherein satisfaction of the delay spread threshold is based at least in part on application of at least one of the first v-smooth filtering process or the second v-smooth filtering process.

A non-transitory computer-readable medium storing code for wireless communications at a first wireless communication device, the code comprising instructions executable by one or more processors to:

• communicate, with a second wireless communication device, control signaling that indicates that the first wireless communication device is scheduled to transmit a beamformed message to the second wireless communication device, and wherein the control signaling includes an indication that the second wireless communication device is to apply channel smoothing filtering to the beamformed message;
• transmit, to the second wireless communication device and in association with the control signaling, the beamformed message via a set of frequency tones, wherein one or both of the beamformed message satisfies a delay spread threshold or a phase alignment of the beamformed message associated with the set of frequency tones satisfies a phase alignment threshold;
• and
• apply a first v-smooth filtering process in a first tone domain to a packet mapped to the set of frequency tones;
• or
• apply the first v-smooth filtering process in the first tone domain to the packet and apply a second v-smooth filtering process to the packet in a second tone domain subsequent to applying the first v-smooth filtering process, wherein satisfaction of the delay spread threshold is based at least in part on application of at least one of the first v-smooth filtering process or the second v-smooth filtering process.
